Stem Guide Replaceable Cartridge Fishing Bobber
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fishing tackle systems, such as bobbers and floats, often damage fishing lines due to sharp edges and require cumbersome adjustments, and lack easy replacement of cartridges like floats, light sticks, and scent sticks without damaging the stem guide or the cartridges.
Innovation Solution
A stem guide system that allows for the easy attachment and removal of replaceable cartridges, such as floats, light sticks, and scent sticks, using a cartridge attachment mechanism that prevents damage to the stem guide and cartridges, and features a buoyant member that can be cut to adjust buoyancy without harming the stem guide or the cartridges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a saw cut is made in the hollow stem of a fishing float to attach a spring clamp, then the bobber can be temporarily attached to the fishing line in fixed line mode, but the sharp edges of the saw cut can weaken and cut the soft flexible fishing lines
Solution Approach 1:
The invention divides the stem into multiple segments or sections, with the hollow stem portion separated from the attachment mechanism. This allows the hollow stem to maintain its structural integrity without saw cuts, while the attachment mechanism is integrated into the float body or stem cap, eliminating sharp edges that could damage the fishing line.
Solution Approach 2:
The invention introduces an intermediary component (such as a stem cap or attachment mechanism) that mediates between the hollow stem and the spring clamp. This intermediary absorbs the stress and provides a smooth transition, preventing direct contact between sharp edges and the fishing line while maintaining the fixed line mode attachment functionality.
2Adaptability or versatility
If a saw cut is made in the stem of the fishing bobber, then the spring clamp can be attached for fixed line fishing, but the stem is weakened and can break during use
Solution Approach 1:
The stem is segmented into a hollow portion and a solid attachment portion, or the attachment mechanism is integrated into the float body rather than requiring cuts in the stem. This segmentation allows the stem to maintain its full structural strength while still enabling fixed line mode attachment through the intact hollow stem design.
Solution Approach 2:
The hollow stem design is made universal by integrating the attachment mechanism into the float body or stem cap, allowing the same hollow stem to serve both slip bobber mode (where the line passes through) and fixed line mode (where the spring clamp attaches to the float body) without requiring separate stem modifications.
3Reliability
If a spring is used in the line stop to prevent the fishing line from sliding, then the line can be held in position, but the spring forms a moving part that can become stuck
Solution Approach 1:
The invention extracts the spring from the line stop mechanism, removing the moving part that could become stuck. The line stop is redesigned as a fixed structural feature of the stem or float body, using geometric constraints or friction-based retention instead of spring pressure, thereby eliminating the reliability issue associated with moving springs while maintaining line position holding capability.
Solution Approach 2:
The line stop mechanism is designed to be self-regulating through fixed geometric features or friction-based retention, eliminating the need for spring pressure. The line is held in position by the inherent structural design of the stem or float body, which provides automatic retention without moving parts that could fail or become stuck.
4Adaptability or versatility
If cartridges like floats, light sticks, and scent sticks are attached to the fishing line, then fishing functionality is enhanced, but replacement of these cartridges is cumbersome and may damage the stem guide or cartridges
Solution Approach 1:
The invention segments the cartridge attachment system into a removable cartridge portion and a stem guide portion. The cartridges (floats, light sticks, scent sticks) are designed as separate, easily detachable components that can be replaced without tools or complex manipulation. The stem guide provides a standardized interface that allows quick insertion and removal, enabling anglers to switch between different cartridge types rapidly without damaging either the cartridges or the stem guide.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient and damage-free replacement of fishing line accessories, preventing line damage and allowing for adjustable buoyancy without compromising the stem guide or cartridges, enhancing fishing flexibility and efficiency.
Implementation Method 1
providing a buoyant member... such that the buoyancy of the buoyant member when cut to a second length is enough to oppose the tendency of the stem guide and fishing tackle to submerse the buoyant member
Data Source
AI summary
The invention relates to a method for adjusting the buoyancy of a fishing bobber. The method includes providing a buoyant member and a stem guide configured to receive the buoyant member, mounting the buoyant member to the stem guide and cutting the buoyant member. The buoyant member is made of a material capable of being severed by a cutting device and having first length, a lower end, and an upper end. The stem guide receives the buoyant member and a fishing line with fishing tackle. The buoyant member is cut such that the buoyant member has a second length shorter than the first length. The buoyant member is cut to a second length such that the buoyancy of the buoyant member when cut to a second length is enough to oppose the tendency of the stem guide and fishing tackle to submerse the buoyant member such that a top surface of the cut buoyant member is adjacent to the surface of the water when the stem guide, buoyant member, fishing line and any fishing tackle are placed in the water.
